The core technical knowledge of the fully automatic computer pattern machine
Obviously, the inherent technology of computer pattern products is related to solving the seamability, functional requirements, operability, reliability, durability, etc. of the sewing machine and the quality of the products. It is the development of the technology of the product itself, achieving high speed and automation. The technical solutions such as specialization and integration are related to the means and methods for implementing the solutions. These constitute the specific content of the core technology of computer sewing machine products. It can be seen that mastering the core technology of industrial computer pattern machines must rely on professional knowledge, including expertise in other related fields. Only by profoundly analyzing and truly mastering the core technology of the product can we develop and design products with independent intellectual property rights, and gradually establish product design database and sewing machine mechanism map through continuous technical accumulation, laying the foundation for further development of industrial sewing machine innovation design. .
Of course, the core technology of the sewing machine product is dynamic and development. With the maturity of the original product technology, the application of new technology and product upgrade, function expansion, application scope change, especially the creation of new stitch forms and so on. The core technology of industrial sewing machines will also change. However, many common technologies can be used for reference and reference when mastering and analyzing the core technologies of specific products. This is especially true when developing serialized products. This illustrates the importance of technology accumulation and experience.
As an example, try to list the core technologies that high-speed lockstitch machines should understand or master.
(1) Lightweight technology
1. Analysis and test technology of main vibration source of casing
2. Lightweight materials and their surface coating technology
3. The influence of the cross-sectional shape of the casing on vibration
(2) Factors influencing the realization of low-tension sewing
(3) Upper thread dynamic tension measurement technology
(four) rotary hook design technology
The industrial computer pattern machine industry has developed a line type standard. The basic types of industrial computer pattern machines that realize various stitches are matured through long-term use, and the type of mechanism tends to be finalized. Product quality improvement, variety development, technical level improvement, and replacement are more consistently based on the original product. The application of mechatronics technology provides more room for product gradual and continuous changes and innovations, but it must also be based on the original products, adding automation, integration or systemic functions. It is unlikely that the basic types of industrial sewing machines will be completely changed. Even if the cam mechanism is replaced by electronic control technology like a cycle sewing machine, it is only a change of control mode, which aims to simplify the mechanism. Reverse design is also an innovative design. It must conduct comprehensive, in-depth and systematic analysis of the existing advanced products using various scientific test methods. The computer pattern machine understands and masters the structural characteristics, mechanism principle, function, quality level and related design parameters of the product. At the same time, the new technologies, new processes and new materials applied in the products are evaluated on the basis of digestion and absorption. Judging the various problems to be improved in the products found in the analysis and the requirements and potential requirements of users and market feedback for product quality, and using this as an innovative design entry point to develop innovative products. Therefore, reverse design is a pioneering, practical and comprehensive product innovation design method.
(I) Market demand Any sewing machine product development comes from market demand. Its guiding ideology is to contribute the most to the development strategy of the enterprise, and the development success rate is the highest. Recognize the marketability, economy and quality of products and make choices to meet the needs of different levels of the market.
(2) Prototype selection Select the base product as a prototype to facilitate the development of serialized products in the future; pay attention to the advanced nature of the prototype; select famous brand products; pay attention to the user's product quality requirements and potential quality requirements; attach importance to the establishment of product data (sample) library .
(3) Prototype evaluation project (different industrial computer pattern machines, evaluation items are different)
Separability evaluation: broken wire, broken needle, jump stitch, floating line, skew line, neat line alignment, stitch tension, uniform high and low speed stitches, sewing material migration, wrinkling, vibration, noise, torque, etc. Functional evaluation: functional parameters and reliability durability evaluation: performance evaluation of key components durability adjustment: adjustability, stability, adjustment range and ease of operation Safety evaluation: operational safety Sewing process design parameters rationality evaluation: sports Assembly evaluation of cycle diagrams, functional mechanism execution component motion diagrams: new materials, new processes, and new technology evaluations such as positioning reference and assembly clearance: feature analysis design evaluation and other (including component structure and size)
Product Difference Evaluation: Characteristic Analysis
(4) The evaluation method is compared with existing products or other advanced products collected, and internal control standards of advanced foreign enterprises. The conclusions drawn are used as technical indicators and evaluation basis for innovative product design.
(V) Examples of innovative solutions
1. Innovative design of feeding mode: lower feeding, needle feeding, upper and lower feeding, differential feeding, variable feeding up and down feeding, new structure of independent movement of upper and lower feeding, comprehensive feeding, roller feeding, etc.;
2. Innovative design of the thread take-up mechanism: cam take-up line, connecting rod take-up line, sliding rod take-up line, rotating disc take-up line, etc.;
3. Innovative design of the needle mechanism: the center crank slider mechanism, the rocker slider mechanism, the link mechanism, the needle bar swing from the fulcrum mode to the translation mode;
4. The design of the upper and lower shaft transmission modes: the connecting rod method, the gear method, the synchronous belt method, and the like, and the innovation of the feeding mechanism.
(6) Confirming the improvement project after the evaluation of the innovative program sample, clearly improving the objectives and technical requirements of the project, and using the product data (sample) library, design database, institutional map and related professional knowledge and experience to complete the specific design plan. And verify the improved part of the physical production, sometimes need to be revised repeatedly, and finally complete the optimal solution.
The above is just a brief introduction to the reverse design process.
Of course, innovative design is improved and fundamental. As long as we establish innovative design concepts, study hard, explore with courage, and continuously sum up experience, our level of innovation and innovation will surely improve. This will effectively promote the breakthrough progress of China's sewing machine industry and accelerate China's pace of becoming the world's largest sewing machine production power.
